Deployment and Evaluation typically represents a larger portion of the exam, as it tests hands-on configuration and validation skills. Architecture and Planning and Network Security Strategy and Best Practices are equally important and often appear together in scenario questions. Review the official exam blueprint to confirm current topic weights.
Architecture decisions made during planning phase directly impact deployment complexity and operational policies. For example, choosing a high-availability firewall pair affects failover configuration, policy synchronization, and monitoring setup during deployment. Understanding this relationship helps you make informed choices in scenario questions.
Direct experience configuring Palo Alto Networks hardware firewalls in lab or production environments is highly beneficial. Prioritize labs covering policy creation, threat prevention settings, interface configuration, and security zone design. If you lack hands-on access, virtual lab environments and practice test scenarios can bridge the gap.
Candidates often overlook security best practices in favor of quick solutions, miss capacity planning implications in scenario questions, or confuse feature behavior across different firewall models. Carefully read scenario questions to identify all requirements before selecting an answer, and verify your choice aligns with both security and operational goals.
Focus on weak topic areas identified during practice testing rather than re-reading all material. Complete one full-length timed practice test to assess readiness and pacing. Review explanations for any missed questions and consult official Palo Alto Networks documentation on those specific topics. Avoid cramming new concepts in the last 24 hours; instead, rest well and review high-level topic summaries.
Which two actions should a systems engineer take when a customer is concerned about how to remain aligned to Zero Trust principles as they adopt additional security features over time? (Choose two)
When adopting additional security features over time, remaining aligned with Zero Trust principles requires a focus on constant visibility, control, and adherence to best practices. The following actions are the most relevant:
Why 'Apply decryption where possible to inspect and log all new and existing traffic flows' (Correct Answer B)?
Zero Trust principles emphasize visibility into all traffic, whether encrypted or unencrypted. Without decryption, encrypted traffic becomes a blind spot, which attackers can exploit. By applying decryption wherever feasible, organizations ensure they can inspect, log, and enforce policies on encrypted traffic, thus adhering to Zero Trust principles.
Why 'Use the Best Practice Assessment (BPA) tool to measure progress toward Zero Trust principles' (Correct Answer C)?
The BPA tool provides detailed insights into the customer's security configuration, helping measure alignment with Palo Alto Networks' Zero Trust best practices. It identifies gaps in security posture and recommends actionable steps to strengthen adherence to Zero Trust principles over time.
Why not 'Turn on all licensed Cloud-Delivered Security Services (CDSS) subscriptions in blocking mode for all policies' (Option A)?
While enabling CDSS subscriptions (like Threat Prevention, URL Filtering, Advanced Threat Prevention) in blocking mode can enhance security, it is not an action specifically tied to maintaining alignment with Zero Trust principles. A more holistic approach, such as decryption and BPA analysis, is critical to achieving Zero Trust.
Why not 'Use the Policy Optimizer tool to understand security rules allowing users to bypass decryption' (Option D)?
Policy Optimizer is used to optimize existing security rules by identifying unused or overly permissive policies. While useful, it does not directly address alignment with Zero Trust principles or help enforce decryption.
Which statement appropriately describes performance tuning Intrusion Prevention System (IPS) functions on a Palo Alto Networks NGFW running Advanced Threat Prevention?
Create a New Threat Profile (Answer B):
Performance tuning in Intrusion Prevention System (IPS) involves ensuring that only the most relevant and necessary signatures are enabled for the specific environment.
Palo Alto Networks allows you to create custom threat profiles to selectively enable signatures that match the threats most likely to affect the environment. This reduces unnecessary resource usage and ensures optimal performance.
By tailoring the signature set, organizations can focus on real threats without impacting overall throughput and latency.
Why Not A:
Leaving all signatures turned on is not a best practice because it may consume excessive resources, increasing processing time and degrading firewall performance, especially in high-throughput environments.
Why Not C:
While working with TAC for debugging may help identify specific performance bottlenecks, it is not a recommended approach for routine performance tuning. Instead, proactive configuration changes, such as creating tailored threat profiles, should be made.
Why Not D:
Disabling irrelevant threat signatures can improve performance, but this task is effectively accomplished by creating a new threat profile. Manually disabling signatures one by one is not scalable or efficient.

A large global company plans to acquire 500 NGFWs to replace its legacy firewalls and has a specific requirement for centralized logging and reporting capabilities.
What should a systems engineer recommend?
A large deployment of 500 firewalls requires a scalable, centralized logging and reporting infrastructure. Here's the analysis of each option:
Option A: Combine Panorama for firewall management with Palo Alto Networks' cloud-based Strata Logging Service to offer scalability for the company's logging and reporting infrastructure
The Strata Logging Service (or Cortex Data Lake) is a cloud-based solution that offers massive scalability for logging and reporting. Combined with Panorama, it allows for centralized log collection, analysis, and policy management without the need for extensive on-premises infrastructure.
This approach is ideal for large-scale environments like the one described in the scenario, as it ensures cost-effectiveness and scalability.
This is the correct recommendation.
Option B: Use Panorama for firewall management and to transfer logs from the 500 firewalls directly to a third-party SIEM for centralized logging and reporting
While third-party SIEM solutions can be integrated with Palo Alto Networks NGFWs, directly transferring logs from 500 firewalls to a SIEM can lead to bottlenecks and scalability issues. Furthermore, relying on third-party solutions may not provide the same level of native integration as the Strata Logging Service.
This is not the ideal recommendation.
Option C: Highlight the efficiency of PAN-OS, which employs AI to automatically extract critical logs and generate daily executive reports, and confirm that the purchase of 500 NGFWs is sufficient
While PAN-OS provides AI-driven insights and reporting, this option does not address the requirement for centralized logging and reporting. It also dismisses the need for additional infrastructure to handle logs from 500 firewalls.
This is incorrect.
Option D: Deploy a pair of M-1000 log collectors in the customer data center, and route logs from all 500 firewalls to the log collectors for centralized logging and reporting
The M-1000 appliance is an on-premises log collector, but it has limitations in terms of scalability and storage capacity when compared to cloud-based options like the Strata Logging Service. Deploying only two M-1000 log collectors for 500 firewalls would result in potential performance and storage challenges.
This is not the best recommendation.

Which initial action can a network security engineer take to prevent a malicious actor from using a file-sharing application for data exfiltration without impacting users who still need to use file-sharing applications?
To prevent malicious actors from abusing file-sharing applications for data exfiltration, App-ID provides a granular approach to managing application traffic. Palo Alto Networks' App-ID is a technology that identifies applications traversing the network, regardless of port, protocol, encryption (SSL), or evasive tactics. By leveraging App-ID, security engineers can implement policies that restrict the use of specific applications or functionalities based on job functions, ensuring that only authorized users or groups can use file-sharing applications while blocking unauthorized or malicious usage.
Here's why the options are evaluated this way:
Option A: DNS Security focuses on identifying and blocking malicious domains. While it plays a critical role in preventing certain attacks (like command-and-control traffic), it is not effective for managing application usage. Hence, this is not the best approach.
Option B (Correct): App-ID provides the ability to identify file-sharing applications (such as Dropbox, Google Drive, or OneDrive) and enforce policies to restrict their use. For example, you can create a security rule allowing file-sharing apps only for specific job functions, such as HR or marketing, while denying them for other users. This targeted approach ensures legitimate business needs are not disrupted, which aligns with the requirement of not impacting valid users.
Option C: Blocking all file-sharing applications outright using DNS Security is a broad measure that will indiscriminately impact legitimate users. This does not meet the requirement of allowing specific users to continue using file-sharing applications.
Option D: While App-ID can block file-sharing applications outright, doing so will prevent legitimate usage and is not aligned with the requirement to allow usage based on job functions.
How to Implement the Solution (Using App-ID):
Identify the relevant file-sharing applications using App-ID in Palo Alto Networks' predefined application database.
Create security policies that allow these applications only for users or groups defined in your directory (e.g., Active Directory).
Use custom App-ID filters or explicit rules to control specific functionalities of file-sharing applications, such as uploads or downloads.
Monitor traffic to ensure that only authorized users are accessing the applications and that no malicious activity is occurring.

Which two methods are valid ways to populate user-to-IP mappings? (Choose two.)
Populating user-to-IP mappings is a critical function for enabling user-based policy enforcement in Palo Alto Networks firewalls. The following two methods are valid ways to populate these mappings:
Why 'XML API' (Correct Answer A)?
The XML API allows external systems to programmatically send user-to-IP mapping information to the firewall. This is a highly flexible method, particularly when user information is available from an external system that integrates via the API. This method is commonly used in environments where the mapping data is maintained in a centralized database or monitoring system.
Why 'User-ID' (Correct Answer C)?
User-ID is a core feature of Palo Alto Networks firewalls that allows for the dynamic identification of users and their corresponding IP addresses. User-ID agents can pull this data from various sources, such as Active Directory, Syslog servers, and more. This is one of the most common and reliable methods to maintain user-to-IP mappings.
Why not 'Captive portal' (Option B)?
Captive portal is a mechanism for authenticating users when they access the network. While it can indirectly contribute to user-to-IP mapping, it is not a direct method to populate these mappings. Instead, it prompts users to authenticate, after which User-ID handles the mapping.
Why not 'SCP log ingestion' (Option D)?
SCP (Secure Copy Protocol) is a file transfer protocol and does not have any functionality related to populating user-to-IP mappings. Log ingestion via SCP is not a valid way to map users to IP addresses.
